ELASTIG FABRIC` Specification of Letters Patent.

Patented Dec. 2, 1913.

To all whom t may concern:

Be it known that I, WALDEMAR Kors, a

lcitizen of the United States, residing at the ticle, and in which .these inelastic sections come between the sewing sections and sections under tension whereby lany elastic strands cut inthe .sewing sections are unaffected in the inelastic or anchored sections,

therefore not affecting the strands of the elastic section under tension.

-In carrying out my invention Itake a strip or length of elastic fabric o r webbing of usual character and at predetermined 1ntervals produce inelastic sections by-saturating the fabric with a foreign substance This foreign substance is preferably an adhesive-unaffected by moisture-which is absorbed by' the warp and weft threads ofthe fabric, filling the inter# stices between the threads and surrounding' the rubber strands and is therefore incorL porated with the fabriej When' dried this material produces more or lessI of a rigid condition of the ,fabrici atv such sections, whereby the elastic strands are anchored in sections coming between the'sewing sections and the elastic parts, 'and the service or life of the elastic parts is unaffected by the sewed connection to a garment orsup Ort. p In the drawing Figure l is a plan representing a section of fabric or webbing made according to my invention; Fig. 2 shows a length of webbing treated to produce predetermined inelastic sections. n

a represents the elastic section or sections, b the inelastic section or sections and c the sewing section or sections. The parts a are elastic fabric or webbing of any suitable character width or length. The sewing section or sections c are also of elastic fabric or webbing of any desired width or length. The inelastic section or sections are of the same character primarily considered, but

of usual character, by treating such parts or sections by saturating the same with a foreign substance in liquidv form. This foreignsubstance in liquid formis absorbed by thewarp and weft threads, ills all the iriterstices between the threads and at the same time surrounds the rubber strands running between the warp and weft threads. This foreign substance in liquid form must 4be of such a character as to dry and become hard, at least to an appreciable extent, and when in this condition the warp and weft threads are substantially glued or held together and the coating of the foreign substance in -liquid form upon the surface of the elastic strands -causes same to adhere to the warp or weft threads and to be firmly secured, held, or in other words, locked in the fabric. This foreign substance in liquid form is preferably an adhesive, unaffected by moisture. I have experimented witlrv a number of substances capable of being absorbed by the warp and weft threads and of perform-A ing the desired function. Some of these substances dry quicker than others. Some of them become harder when dry than others, but any substance in the form of a gum .taken up by liquid substance capable of dry- 111g and more or less evaporating, will proberform the desired oilice or function.V

`frangible in any sense of the'word. These inelastic sections thusproduced come between the length of fabric or webbing to which tension in use is to be applied andon the other side-the sewing sections which are comparatively short. f

1 I t is quite apparent that when the fabric or webblng is V.attached to a corset, garment or other support by sewing the sewln sections thereto, that if the rubber stran s are cut, it can make no possible difference, for

the reason that the fabric or warp and weft threads of the sewing section are sucient to sew the material in place and hold it, and that if these threads are cut such condition "does not affect the elastic `*strands inthe narevproduced in the elastic fabric or webbing elastic sect-ion, also does not aiect the elastic strands in the sections to be put under tension beyond the inelastic section.

The elast-ic section or sections may be of any length. The inelastic and sewingy sections should be of a width or length suficient only to perform the functions rovided therefor. The elastic fabric or we bing of my invention may be made insubstantial endless lengths to be cut up and when cut up each part comprises, an elastic section and' sewing section and an intermediate in elastic section.

The foreign substance in liquid form or liquid adhesive to be dried, ispreferably of such character as to be unaffected by moiscorporated in the fabric or webbing, where-- by the elastic warps are held or anchored in the intermediate section and the tension applied to the other elastic section is not influenced by thecondition of the elastic warps in the section that is attached in the garment.

2. An elastic fabric or webbing having A spaced elastic sections or parts which come at the respective ends of the webbing, one of which is short and the other of which is long, and the short one of which is adapted to be employed as a sewing section or sec- ,tion to be sewed or attached to a garment, and an intermediate, section made. inelastic by a dry adhesive incorporated in the fabric or webbing, whereby theelastic warps are held or anchored in the intermediate section and the tension applied to the other elastic section isv not influenced by the condition of the elastic warps in the section that is attached in the garment.

3. A length of elastic fabric or webbing treated at predetermined intervals and for a predetermined area with `'a foreign substance in liquid form whichv fills the interstices surrounding the elastic" strands and is absorbed and surrounds the warp and weft threads and when dry locks the elastic strands in place and so forms the inelastic section, and said length of'elastic webbin adapted to be severed at predetermine places to form varying lengths of elastic fabric, in which there are elastic sections, at each side of the inelastic section formed as described, and one of which elastic 'sections is adapted for attachment as 'a sewing section to a garment.
